My drivers window doesn't go drop down slightly when I open and close the door. on 2004 Audi TT Quattro

Some time ago (3 months), my drivers window stopped going down automatically, when I just hit the button (it will go down if I hold the button down). And then, suddenly one day it did, and then a couple of weeks later it stopped again. It has not gone down automatically since. And then one morning, I noticed the drivers window stopped dropping down slightly when I opened the door.

I'm in the same boat! Does anyone know what's going on?
